The frame of the machine supports a tank It in which the washing liquidll or bath-is contained. Theframe comprises side uprights It, It J atthe rear end of the frame, which converge toward the top of the frame,where they are rigidly connected by a stringer 20. A lower stringer 2|is rigidly connected with. the lower portions of the uprights. The framefurther comprises front uprights 22, 28 which converge upwardly. Thelower 50 ends of therespective uprights serve S 1688 and 24 providedwith holes to receive lag screws to hold the machine inplace.

Upwardly and inwardly sian as side plates 25.

it are rigidly connected with the uprights and 5s drums having diiiersoat its ends to the side plates.

The tank l6 has a stationary cover 36 and a movable cover 37. The tankhas converging end walls 38, 33, an intermediate longitudinallyextending and cross-sectionally arcuate wall 40 at its outercircumference, and central end walls ll, 42, all of which are rigidlyconnected together. The tank preferably has the form of the sectors oftruncated double cones whose bases are presented .toward each other'andhave the sector of a cylinder between them.

The top plate 21 is provided with a recess at its inner end, the wall 63of which is located about the inner truncated end of the tank,encompassing the inner end wall 4| of the tank and the inner end of theinner truncated conical wall 38 thereof. The side plates 25, 26 arerespectively provided with recesses 84, at their front ends, each ofwhich is provided with a forward outwardly and downwardly slanting wall45, and an inwardly presented lateral wall 46, the balance of the innertruncated conical wall 38 registering with said walls 45, and thecylindrical wall 40 registering with the lateral walls 46. The inner endwall II, the inner truncated wall 38 and the arcuate wall 40 of the tankare rigidly connected with the walls 43, 45, 46 in the top plated! andside plates '25, 26. A front cross plate 41 has a recess 48 at its upperedge, the wall of which forms a seat for the front end of the arcuatewall of the tank. This cross plate is rigidly connected with said tankat said arcuate wall and. with the front uprights 22, 23. All .of therigid connections herein mentioned may be made by electrical or otherwelding. The frame and the tank may be integrally connected to form arigid body. The side plate 26 is provided with an opening giving accessto the interior of the frame and the devices there- This opening isnormally closed by a closing plate 49 releasably secured to said sideplate.

access is had to a 51 rotatable in the tank and to the interior of thetank. The stationary cover or section 36 and the movable cover orsection 31' of the cover respectively have converging end intermediatelongiand cross-sectionally arcuate walls 62, 63 at their outercircumference. sections of the cover preferably respectively have theform of the sectors of truncated double cones whose bases are presentedtoward each other and having the' sector of a cylinder between them. Thesections of the cover one within the other when is opened. The tank andthe covers when closed are formed preferably substantially like a pairof truncated cones having with a flange II. The lower edge of the sta- Ipreferably telescope the movable section their bases presented nuts 67.The front margin of the stationary cover is provided with a flange 68for strengthening-the same. The normally lower margin of the movablecover is provided with a flange 63, which rests on the front portionj'of the flange 5 '65 of the tank when the cover is closed. The movablecover is provided with a stop 10 which coacts with the front margin ofthe stationary cover for limiting inward movement of the movablesection. The flanges 65, 86, 68 and 69 ex- 10 tend along the cylindricalportion and the slanting end portions of the walls of the tank andcovers and terminate preferably at the truncated end portions of saidtank and covers.

The drum v5'! has a cavity H in which the 5 tripe or other material isarrangedto be placed for being washed. The drum comprises a plu- Angles16 are formed between the converging end walls '13, 14 and thecircumferential walls 25 15. Angles 71 are formed between adjoiningmargins of the adjoining converging end walls, and angles 18 are formedbetween adjoining margins of adjoining circumferential walls 15.

The sections drums, for example, inches in diameter, are six suchangular sections; larger drums, in the neighborhood of forty-eightinches in diameter, are preferably provided with eight'such sections,

tripe or other material therewith. 55

The walls of the drum are provided with perforations 85, preferably soformed that the metal tially the areas of the walls of .the drum and arepreferably close together and of such size as to act upon and bend theupstanding walls of the 70 honey-comb portions of the tripe, and toscrape and remove the fat, slime and deleterioussubstances from thetripe andother materials, especially duringthe contracting and expandingmovements of the tripe and other materials into and 7 between said huband the inner end of the housv out of the Converging spaces between theconverging' walls of the drum.

I prefer to mount the drum such manner that the tripe and othermaterials in the drum may move across the axis of rotation of the drum,

whereby freedom of'movement of the tripe and other materials in the drumis enhanced, and the force of dropping of the same in-the drum isincreased, and washing action is imparted .to the tripe and othermaterial which would otherwise not take place, and I therefore mount thedrum on a shaft which does not extend through the drum but projectssolely from one end of'the drum to support and rotate the drum.

Thus there is a shaft 81 whi h is mounted in bearings 98, 89, shown asroller bearings, in a housing 90 secured to the top 21-of the frame bymeans of bolts 9|. These rollers are preferably radial and end thrustrollers, inclined in opposite directions at the respective ends of theshaft, the inner races of the bearings being held outwardly by shoulders92 on the shaft, and the outer races of the bearings being held inwardlyby the inner ends of housing ends 93, 94, flanges 95 of which arerespectively secured to the respective ends of the housing 90 by bolts96. The housing ends respectively contain lubricant seals 91 to preventseepage of lubricant and cleansing liquid past the same, to protect thebearings and the contents of the tank.

v The shaft is suitably driven, as by means ofan electric motor IIIIadjustably mounted on a motor plate. I02 having lugs I03 pivoted on apivot rod I04 supported in the stringers 2I and 39 of the frame. Boltsand nuts I05 adjustably secure the feet I 06 of the motor frame to themotor plate. The motor is provided with a pulley I91,

about which and a pulley I08 a fiexible drivingband I99 is located todrivethe pulley I08. The

.latter pulley is fixed to-an intermediate shaft II I,

sprocket wheels and the flexible driving bands may be sprocket chainsthereabout. The pulleys and the flexible driving connections form speedreducing gearing between the motor and the drum.

One end of the drum is provided with a central end 'plate I23, whichforms' an attaching plate, and is fixed to the; inner ends of theangular end wallsof the drum at that end, as by welding or othersuitable means, the inner ends of the strengthening ribs being alsopreferably secured to the inner face of theattachlng plate, as bywelding, so as to strengthen the drum at its journaled end. A collar I24is provided with a flange I25, and is keyed to the shaft. 31 by a keyI26, so as to rotate with the said shaft. The

shaft 81. The shaft is held endwise by the roller bearings 88, 89, tofix the position of the rotary path of the drum and to provide freerotation ing end 94.

The drum is provided with a charging opening I3I surrounded by a wallI32, shown as a band. This charging opening is at the axis of rotationof the drum and surrounds the same. The proximate ends of the sectionsof the slanting outer end wall 14 of the drum are secured'to the wall.

with a charging opening I35, which is preferably in an annular band I36,forming the wall of said opening and provided with an outer annularflange I31: The outer. central end wall,

42 of the tank is at its central portion provided with a recess I38 forreceiving the lower portion of the band I36, the flange I31 of thelatter being secured to this end wall of the tank, as by welding. Thecharging band I36 surrounds and is spaced from the axis of rotation ofthe drum.

A closure I4I is-provided for the charging openings and is exemplifiedas a plate provided with upper and lateral hooks I42 extending inwardlybeyond the closure plate and' arranged to be hooked over the outermargin of the flange I31. The closure plate is provided with a handleI43 for manipulating the same.

The movable cover is pivotedabout the axis of rotation of the drum. Ithas an inner bearing I45 (Fig. 6) received partway about the outerperiphery of the housing end 94 and an outer bearing I46 (Fig. '7)received partway about the wall I36 of the charging opening of the tank,these bearings-being concentric with each other and so arranged that thesame may be lifted off of their respective journal supports, after thestationary portion of the cover has been removed. The inner margins ofthe movable cover may be provided with a strengthening strip I41. Theouter faces of the central end walls of the movable cover (Figs. 4, 6and 7) are preferably provided with ridin'g strips I48, I49 respectively.arranged arcuately about the pivotal axis of the ment of the movablecover.

A suitable washing liquid is provided in the tank, as by means .of aninflow pipe I5I, threaded into a receiving port I52 in the tank andcover to separate the movable cover endwise from the stationary coverand to provide ease of movehaving pipes I53, I54 connecting therewith,the

latter being respectively steam and water pipes provided with valvesI55, I53 for regulating the proportions of fluid supplied to the tankandthe heat of the washing liquid in the tank. An outflow port I51 isprovided in the bottom portion of the tank and has an outflow pipe I58connected therewith provided with a gate valve I59 for shutting off andregulating the outflow of liquid from the tank. The normal height of thebath or washing liquid in the tank is represented by the. dotted lineI6I.

A modification, shown in Figs. 10 and 11, (in

which the elements are indicated by similar but primed referencenumerals), is provided with means by whlchthe level of washing liquid inthe ,tank is automatically maintained. The outflow 'pipe I62 is providedwith a normally upwardly extending branch I63, which is open at itsupper end at the desired level of liquid in the tank, excess washingliquid flowing out of this open upper end, the supply of liquid,obtainedthrough pipesand valves as herein just described, being so regulated. asto maintain the level of the liquid in the tank. branch iii is pivotedand is arranged to be tilted downwardly, so as to extend downwardlybelow the level of the tank, asshown in dotted linesin Figs. 10 and 11,for discharging washing liquid from the tank.

In the operation of my improved device, the material, for instance,tripe, is charged into the drum through. the axial feeding opening I inthe tank andthe axial feeding opening |3I .in the drum. It will benoticed that the walls of these openings are shown close together, endto end, so as to practically makes a continuous wall. The drum is filledwith the material to be washed to about the level of the lower portionof these openings, which may take place during rotation of the drum,thus subjecting the material to the action of the bath during chargingof the same and preliminarily coating all surfaces of the material withthe cleaning liquid, thereby aidingin the cleaning and expediting thecleaning operation.

The upwardly extending The drum having been provided with thecharge oftripe or other material to be washed, the closure or gate ill is closedand rotation of the drum continues, or rotation of the drum may now beinitiated, the speed'of rotation being such as is most suitable for thewashing operation and suitable for the size of drum and the character ofthe material being washed.

During this rotation, the tripe, or other material, is carried with themovement of the drum and the material is moved through the washingliquid, which thoroughly surrounds all the surfaces of the materialrandthe material is-carried with the drum in the directio'n of rotation ofthe latter, some of it sliding and rolling in the drum, causing frictionand rubbing between the layers of tripe or other material, and be-'tween the tripe or other material and the walls of the drum. Duringthese movements there is also contact between the tripe or othermaterial and the angularly arranged section of the drum, whose walls arepresented at various angles to the movements of the tripe or othermaterial in directions different from'the rotary movement of the drum,so as to cause additional rubbing between the surfaces of the tripe orother material and between the latter and the angular portions ofthewalls of the. drum, all of which aids incleaning the surfaces of thetripe or other material and in removing the deleterious matter held bysuch surfaces from the tripe or other .material, and especially from thehoney-combed and other recesses in the tripe.

During this action also'thereis'rubbing contact between the material andthe deflectors -8ll, causing rubbing action between the same, duringwhich, as well as during the rubbing actions previously explained, thereis movement between the surfaces of the tripe and other materials, andbetween the latter and the deflectors in the drum which are the resultof differential movements between the same in the same directions and inreverse directions between the'same, due, for instance, to reversedroppings of raised portions of the tripe or other material, and therelatively more rapid movements of the same during such droppings, allof which aids in the washing action upon the tripe. The cover ismaintained closed during these operations, retaining the heat of thebath in. the tank and preventing splashing during the scalding, scrapingand cleaning operations.

This washing action is further enhanced ,by

on the outflow pipe I62 walls of the drum, acting with a scraping andcleaning function especially on the tripe, to wash the deleterioussubstances from the surfaces of the tripe and to cause projections ofthe walls of the perforations into the recesses in the surfaces of thetripe presented by the honey-combed formation of large portions of thetripe and to cause the bending of the walls of recesses in the tripe andthe suction created by the coaction between said recesses and therecesses in the inner surface of the wall of the drum.

Much of the tripe and other material is carried with the drum during therotation of the latter, the tripe dropping back into the lower portionsof the drum and into the bath by gravity as the tripe and other materialis rising, or the-tripe and other material may be carried with the drumduring its rotation so as to move with the drum until the tripe or othermaterial reaches the upper portion of the travel of the drum, or duringsuch travel, the tripe or other material which was raised, drops to thebottom portion of the drum, which causes a compacting and rubbingaction, especially between the tripe so dropping and the layersthe'reofin the lower portions of the drum. The freedom of the interior of thedrum from an obstructing shaft.

honey-combed formation thereof and their coaction with the convergingwalls of the drum. As

the material, especially tripe, is moved upwardly with the drum duringrotation of the latter, it will expand by reversal of the force ofgravity,

and the raised material, especially tripe, will forcefully drop to thelower portion of the drum, and in expanding and dropping, will causereverse action between its surfaces,'as when releasing the pressure onthe sponge in cleaning the same, to be immediately followed by anothersqueezing action upon the same by its dropping and moving by gravityinto the succeeding contracting lower portion of the drum, enhanced bythe coaction between the wall of'the drum and the same, due to thecross-sectional angular relations of such walls and the angularrelations between the sections of the walls about the drum.

The inflow of washing liquid may continue during this action and thetank be partially or wholly drained at intervals, by'operation of thevalves in the inflow pipes and the operation of the valve in the outflowpipe, so as to cause discharge of the detrimental contents thereof,washed and cleaned from the material, or such.

and the similar. to the cross-sectional contour of the drum, but oflarger dimensions, provides a body of washing liquid between the tankand the low- 1 er'portions of the drum of substantially equal widththroughout for controlling the movements of such washing liquid and-thecurrents thereof due to rotation of the drum and the action of thematerial substantially in line with and contrary to such movements ofthe washing liquid, so as to induce currents in the washing liquid whichwill be most eiiective in the cleansing operation and will minimizemovements of washing liquid beyond the sphere of action of the drum.

cleaned by introducing suitable sprays into the tank through the opening56 in the tank and through the perforations in the drum, as well asthrough the charging openings in the tank andthe drum, during all ofwhich the drum may be rotated in a bath of cleansing fluid in the tank.

Specifically, tripe may, by employment of my improved device, bethoroughly cleansed in a continuous operation. The tripe may be. chargedinto the rotating drum through its axial opening into a scalding bath toscald and cleanthe tripe, the bath being agitated by the rotating drumto thoroughly mix its ingredients, and the tripe being subjected to thescalding and cleaning for a suitable length of time, said ten minutes,throughout which the drum is caused to rotate.

' The bath and its accumulated impurities are then discharged and a hotcleaning bath substituted for thoroughly cleaning the tripe, therotations of the drum continuing during such change and thereafter, tothoroughly agitate the bath and clean the tripe, this cleaningcontinuing for a further suitable period of time of approximately tenminutes. The latter bath with its accumulated impurities is thendischarged and a chilling rinsing bath substituted therefor and thetripe .sub-

jectedto it for a further suitable period of approximately five minutes,during continuing rotation of the drum, whereu'pon'the tripe may bepulled partially through the axial openings and spread and inspectedwhile removing the same,

all during continuing rotation of the drum, and, if any of the tripe isfound to be not sufficiently clean, it may be pushed back into the drumfor further cleaning.

After the cleansed and chilled tripe has been removed from the drum,through its axial charging opening, hot water or steam and cleaningingredients are charged into the rinsing bath to prepare it for the nextscalding bath for the next batch of tripe during further continuingrotation of the drum. The operation of the machine is continuous duringand between cleanings of successive batches of tripe, resulting in greateconomics and insuring thorough cleansing.

The drums when cleaning tripe are rotated preferably at approximately anouter circumfer-' ential speed of some sixty-four hundred feet perminute. In practice the perforations of the drums may as an example befive-eighths to one and a half inches in diameter and distanced from.each other in staggered relation so that their centers are one and afourth to two and a' half inches apart, and the walls of the flanges ofthe apertures extend one-eighth to threeeighths inches high.-

. If desired, the charging end of-thedrum may be provided with asupplemental bearing supstub, ends which are 'journaled in said sides ofsaid channel.

The wall or sleeve 232 of the charging opening 23l of the drum 251 isextended axially outwardly through a registering opening 208 in thecentral end wall 242 and the central openingZM to form 'a charging mouthfor the drum. The wall or sleeve 232 rides on the rollers "201. The

closure 2 is supported by its hooks 342 on the flange 205.

My improved device comprises simple means whereby large quantities oftripe and other material may be cleaned and inspected within smallcompass and during continuous operation, whereby parts within the drumwhich might retard cleansing action on the tripe, are avoided, andwhereby drums of large capacity may be mounted in the tank inoverhanging relation and the charging and discharging of the drum maytake place at a. convenient elevation, and a continuous wall for thecharging mouth into the drum be provided.
